Ponder, N dmont Region Coordinator Habitat Conservation Pro&= DATE: 21 May 2001 SUBJECT: Pre-construction Notification Application for Cardinal Lake Subdivision, Durham County, North Carolina. DWQ rv: 010496 Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the subject pre-construction notification. A site inspection was conducted on 4 May 2001 by NCWRC biologists to f Wher assess impacts to fish and wildlife resources. Our comments are provided in accordance with provisions of the Clean Water Act of 1977 (as amended), the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661- 667d), and North Carolina General Statutes (G.S. 113-131 et seq.). The applicant proposes to impact 186 linear feet of stream and associated wetlands with culverts and fill for access roads and sewer line construction in a 140-acre residential development, Cardinal Lake Subdivision. The streams that run through the project are tributaries to Chunky Pipe Creek. Chunky Pipe Creek, designated as WS-IV-NSW, is a tributary of Falls Lake and is within the Neuse River basin. The applicant also proposes to fill 6,542 square foot of Lake Unity to prevent sewer lint encroachment within Zone 1 of the Neuse River riparian buffer area. According to the site map, there are a number of lots that have streams running through them or are located within the Neuse River buffer zone. Riparian areas were observed to consist of mixed hardwoods, pines, shrubs, and grasses. .

Stream piping reduces the infiltration of storm water and associated pollutants, as well as the dissipation of stream energy. Piping a stream and placing it underground obviously removes both aquatic and terrestrial habitat. Existing uses by wildlife arc lost and future opportunities to improve aquatic diversity, even if water quality improves, are precluded, Likewise we are concerned about impacts to wetlands due to their wildlife habitat value and the well-known beneficial functions that they provide for (food control and water quality protection. Changes in land use from a primarily forested area to a suburban landscape may exacerbate channel degradation due to increased stormwater runoff. However, we will not object to the project provided that the following recommend conditions arc incorporated into the permit to reduce impacts to fish and wildlife resources. Remaining wetlands and streams on the site should be protected from additional impacts by placing them in a permanent conservation easement to prohibit filling, draining, flooding, and excavation. 2. Li order to minimize stream impacts, while retaining some measure of wildlife habitat, we recommend a 100-foot undisturbed, native, forested buffer along perennial streams, and a 50-foot buffer along intermittent streams and wetlands. Maintaining undisturbed, forested buffers along these areas will minimize impacts to fish and wildlife resources, water quality, aquatic habitat both within and downstream of the project area, and help prevent the extirpation of endangered and threatened species. In addition, wide riparian buffers are helpful in maintaining stability of stream banks and for treatment of pollutants associated with urban stormwater. Whereas. a grassed buffer, particularly fescue, is a vegetated buffer but will not provide the necessary and highly valuable functions as discussed for forested buffers. 3. Use bridges for all permanent roadway crossings of streams and associated wetlands to eliminate the need to fill and culvert. If culverts must be used, the culvert should be designed to allow for fish passage. Generally, this means that the culvert or pipe invert is buried at least one foot below the natural streambed. If multiple cells are required, the second and/or third cells should be placed so that their bottoms are at stream bankfull stage (similar to Lyonsfield design). This will allow sufficient water depth in the culvert or pipe during normal flows to accommodate fish movements. If culverts are long, baffle systems are required to trap gravel and provide resting areas for fish and other aquatic organisms. If multiple pipes or cells are used, at least one pipe or box should be designed to remain dry during normal flows to allow for wildlife passage. In addition, culverts or pipes should be situated so that no channel realignment or widening is required. Widening of the stream channel at the inlet or outlet of structures usually causes a decrease in water velocity causing sediment deposition that will require future maintonance. Finally, riprap should not be placed on the streambed. N.CWRC,HCP,FRLLS LRKE TEL:919-528-9859 may 21-ul 1?):20 NO.uui r.U4 Page 3 21 May 2001 Cardinal Lake Subdivision VWQ ID: 010496 4. Locate sewers and other utilities as far away ftm creeks as functionally possible and minimize stream crossings. It is preferable that sewers be located outside the riparian buffers. The construction of roadways in new neiihborhoods can produce short-term direct impacts as well as long-term cumulative effects. Increased stormwater runoff can accelerate erosion of stream banks and scouring of the stream chaimel. Additionally, the pollutants (e.g., sediment, heavy metals, herbicides, pesticides, and fertilizers) washed from roads and urban landscapes can adversely affect and extirpate species downstream of developed areas. Grassed swales in place of curb and gutter and on-site stormwaler management (ix, bioretention areas) can be installed to produce no net change in the hydrology of the watershed and are recommended. These designs often cost less to install and significantly reduce environmental impacts from residential development. Many of these recomracudations have beea applied in Maryland in efforts to protect the Chesapeake Bay from water quality degradation, Thank you for the opportunity to review this pre-construction notice.

Insufficient evidence is present in our files to conclude that your project must be built as planned in waters and/or wetlands in accordance with 15A NCAC 2H .0506. Therefore, unless modifications of the proposal are made as described below, we will have to move toward denial of your 401 Certification as required by 15A NCAC 2H .0507(e) and will place this project on hold as incomplete until', we receive this additional information, we are requesting (by copy of this letter) that the U.S. Army Corps of Engineers place your project on administrative hold. Please provide us with information supporting your position that states your project must be constructed as planned and that you have no practicable alternative to placing fill in these waters and/or wetlands. Specifically can you 1. Provide the complete mailing address of the owner? 2. Can the road crossing (1,400 square feet of impact) be shifted to avoid the wetland fill [sheet 21, 3. Can the sewerline be shifted to avoid the lake fill and buffer impact? 4. Sheet 6 Is unintelligible. Please submit a clearer map. 5. Can the lot line be shifted to allow the sewer line without Zone 2? [sheet 7]? 6. Can the lot line shifted to allow the sewerline without impacting Zone 2 [sheet 8]? 7. Also please discuss whether these roads are public and therefore allowable under local water supply protection rules. Any documentation such as maps and narrative that you can supply to address alternative designs for your project may be helpful in our review of your 401 Certification. Please respond within three weeks of the date of this letter by sending a copy of this information to me and one copy to Steve Mitchell at the Raleigh Regional Office at (919) 571- 7400. If we do not hear from you in three weeks, we will assume that you no longer want to pursue this project and we will consider the project as withdrawn.

It is approximately 140 acres in size and is located approximately 0.5 mile southwest of the Fletcher's Wetland Delineation/Perm itting/Mitigation Soil/Site Evaluations On-Site Septic Systems Environmental Assessments/Audits Neuse Basin and Watershed Buffer Evaluations Groundwater Hydrology Endangered Species Western Branch Offices: (828) 635-5820 - (828) 312-7902 - (704) 516-3922 April 2, 2001 S&EC Project #: 99-4512 Page 2 Chapel Road (SR 1815) and Cheek Road (SR 1800) intersection. Please refer to the attached map (Figure 1) for the location of the proposed project on a USGS topographic quadrangle. S&EC delineated the wetlands and jurisdictional waters present on the subject property in September 2000. Mr. Steve Mitchell, of the NC Division of Water Quality, conducted an on-site determination on October 11, 2000, and found that features "A" and "B" are not subject to the buffers (see attached buffer letter/map). Mr. Mitchell also determined that the other unnamed tributaries to Lake Unity and Chunky Pipe Creek, features C, D, E and F, are subject to the buffers. The proposed project involves road crossings of two intermittent streams and three wetlands; sanitary sewer crossings of two intermittent streams and three wetlands; and discharging fill into Lake Unity to allow the installation of a sanitary sewer line to serve the subdivision. Table 1 (below) itemizes and provides a description of each proposed impact to waters of the US. Please refer to the attached Wetland and NRB Impact Maps (9 sheets) for the location of each impact.

The USACE's current policy requires applicants to avoid and minimize wetland and stream channel impacts to the maximum extent practicable and may require compensatory mitigation to offset unavoidable losses of waters of the US when impacts exceed the thresholds for notification (0.10 acre) or if a discharge causes the loss of any open waters. The applicant requested a detailed delineation of wetlands present on the property prior to site plan development in order to avoid jurisdictional wetlands to the maximum extent practicable. However two beaver impoundments of tributaries north of Lake Unity separate the eastern and western portions of the property, making it necessary to impact these jurisdictional areas with road crossings to provide access to the site from Fletcher's Chapel Road (see impact map, sheets 2 and 3). The remaining road crossing of an intermittent stream is required to provide lots 500 and 501 with access (see impact map, sheet 4). All proposed road and sewer line crossings are perpendicular to wetlands and stream channels. As mentioned above, the applicant proposes to discharge fill into Lake Unity and create a new lake edge to allow for the installation of a sanitary sewer line. Topographic constraints make it necessary to place this sewer line adjacent to Lake Unity along the rear of lots 235 - 239 (see impact map, sheet 3). The creation of a new lake edge will allow the sewer line to remain in this topographic position without encroaching on Zone 1 of the Neuse River Buffer around Lake Unity. Please refer to the attached 3/28/01 letter provided by Jason Bertoncino of Withers & Ravenel for further explanation of impacts to Lake Unity. Of the 140 acres on site, the applicant proposes to preserve over 40 acres of open space, not including Lake Unity or the pond east of Lake Unity. Of the 15.977 acres of wetlands and waters of the U. S. that exist on property, the applicant April 2, 2001 S&EC Project #: 99-4512 Page 4 proposes to preserve 15.576 acres and impact only 0.401 acre. The applicant will also maintain vegetative buffers on the tributaries to Lake Unity and Chunky Pipe Creek, as required by the NRB Riparian Buffer Rule. Because the applicant plans to preserve 15.576 acres of the 15.977 acres of wetlands and waters of the U. S. on-site and maintain vegetative buffets on-site as required by the NRB Riparian Buffer Rule, and because the applicant will minimize impacts to wetlands and stream channels by utilizing perpendicular road and sewer crossings, S&EC does not believe further compensatory mitigation should be required by the USACE for this project. NC-DWQ's current policy requires written concurrence for wetland impacts greater than 1/3 acre and stream channel impacts greater than 150 linear feet per tributary under NWP 39. Because the permanent impacts to wetlands under NWP 39 are 0.353 acre, S&EC requests written concurrence that the project complies with the 401 Water Quality Certification (WQC) associated with NWP 39. As per personal communication between Mr. Kevin Martin (S&EC) and Mr. John Dorney (NCDWQ), the applicant's proposal to discharge fill material into Lake Unity to allow for the installation of a sewer line would be in compliance with the buffer rules if the filled area is re-vegetated. (see impact map, sheet 3). Topographic constraints make this sewer line placement necessary, and lake fill will prevent the sewer line from impacting zone 1 of the riparian buffer around Lake Unity. Please refer to the 3/28/01 "no practical alternative" letter (attached) prepared by Jason Bertoncino of Withers and Ravenel for further explanation. NCDWQ's current policy does not require mitigation for wetlands for impacts below 1 acre and for less than 150 feet of channel per stream under Nationwide Permit 39. Because the impacts for this project are below these thresholds (see Table 1), S&EC believes wetland or stream channel mitigation should not be required by NC-DWQ. All sewer line crossings of wetlands and stream channels are perpendicular and meet the WQC conditions issued for NWP 12. Table 2.

Current NC-DWQ riparian buffer policy requires applicants to obtain buffer approval for non-perpendicular impacts to Zone 2 of the NRB riparian buffers. S&EC requests buffer April 2, 2001 S&EC Project #: 99-4512 Page 6 approval for 11,974 sq. ft. (0.275 acre) of non-perpendicular sewer line impacts to Zone 2 of the NRB riparian buffer around Lake Unity. Topographic constraints make it necessary to impact Zone 2 of the buffer around Lake Unity in four separate locations with sewer lines that parallel Lake Unity (see sheets 3, 7, 8, and 9). Please refer to the "no practical alternative" letter (attached) from Jason Bertoncino of Withers and Ravenel for further explanation of these impacts. Current NC-DWQ policy allows road crossings without stream channel or riparian buffer mitigation if the impacts are less than or equal to 150 linear feet of stream channel or 1/3 acre of riparian buffer per tributary. Because project impacts are below these thresholds (see TablesI and 2), S&EC believes that stream channel or riparian buffer mitigation should not be required. Because the two sanitary sewer crossings of buffered streams are perpendicular and impact less than 40 linear feet of riparian buffer, they are classified as exempt activities by the NRB Riparian Buffer Rules.

Description of proposed work including discussion of type of mechanical equipment to be used (attach plans 81/2" x 11" drawings only): The pro,ject entails construction of a residential subdivision using conventional heavy equipment. 13. Purpose of proposed work: The purpose of the project is to provide road and sewer service to a residential subdivision in eastern Durham 14. State reasons why it is believed that this activity must be carried out in wetlands (include any measures taken to minimize wetland impacts): The applicant requested a detailed delineation of wetlands prior to site plan development in order to avoid jurisdictional wetlands to the maximum extent practicable. However, tivo beaver impoundments and an intermittent stream north of Lake Unity separate the eastern and western portions of the property, making it necessary to construct two road crossings to provide access to the property from Fletcher's Chapel Road (see impact map, sheets 2 and 3). Also, an intermittent stream on ttie southeastern end of the property separates lots 500 and 501 from the remainder of the subdivision, making a road crossing necessary to provide access to the lots (see sheet 4). In order to minimize impacts, all proposed road and sewer crossings will be perpendicular to wetlands and stream channels. In addition to these impacts, the applicant proposes to discharge fill into Lake Unity to allow construction of a sanitary sewer line parallel to the western bank of the lake (see sheet 3) The sewer line must be placed in this position due to topographic constraints, and relocating the lake edge will allow construction of the sewer line outside of Zone 1 of the Neuse River Basin Riparian Buffer. Please refer to the attached letter prepared by Jason Bertoncino, of Withers and Ravenel, for more information regarding these impacts. 15.

The isolated Zone 2 impacts referenced in this letter are shown on sheets 3, 7, 8 & 9 of the attached proposed impact map package. We feel it should be noted that the proposed 140 acres residential subdivision includes several features that promote water quality. These features two large water bodies that will control peak runoff rates, over 40 acres of protected open space and over 22 acres of tree preservation areas. In addition the layout for the proposed subdivision has been completed in a manner to limit stream crossings while providing the required connectivity and design standards of the reviewing local government agencies. All of the proposed isolated Zone 2 impacts are related to the proposed sanitary sewer system. In our opinion the impacts while minimized are necessary due to topographic constraints. Relocation of the sanitary sewer systems out of Zone 2 would result iii significantly deeper infrastructure that would not only require a wider swath of vegetation disturbance during initial construction but would further increase the swath of disturbance should any future maintenance be required by the City of Durham. The most critical of these areas are shown on sheet 3 of the attached impact map package immediately south of the adjacent roadway crossing. Side slopes of approximately 20% are present in this area. As a result, we are proposing limited lake fill in conjunction with this sanitary sewer installation. The proposed fill is a requirement of the local government to provide a minimum "dry" area on either side of the sanitary sewer installation. We endorse this requirement, as this area, (to be re-vegetated as a part of this project); will provide a buffer area between the lake and any future maintenance and a more suitable slope condition to provide diffuse flow through the riparian areas. We offer this information for you use in the permitting process. Please advise should you require any additional information. We appreciate your continued assistance regarding this project.

This project was initially referenced by the Raleigh Regional Office as NBRRO 00-292. The features represented on the Durham County Soils and the USGS Northeast Durham maps were evaluated to determine their subjectivity to the Neuse Buffer Rule. As a result, it was determined that there several features (streams) present on the property that are subject to protection under the Neuse River Basin: Nutrient Sensitive Waters Management Strategy; Protection and Maintenance of Existing Riparian Areas, Administrative Code T15A:02B.0233 (NCAC 0233). The unnamed tributaries to Unity Lake and then Chunky Pipe Creek that are subject to the Neuse Buffer Rule, are delineated on the map received by this Office. This letter only addresses the applicability of the Neuse Buffer Rules.

DOT must follow their document "BMPs for the Protection of Surface Waters" 000894 (DOT, Lincoln Co.) - the project is in WS-II. DOT must follow their document "BMPs for the Protection of Surface Waters" ?????? (no number assigned, L. Russell Bennett of Carolina Foxglove LLC, Jackson Co.) - the project is in WS-ill. If this road is a private road, then it will need to go through the variance process with Jackson Co. Planning Dept. If it is a public road, road crossings are allowed if no practical altemative exists. Plus BUA must be minimized, stormwater diverted away from surface waters, and DOT must follow their document "BMPs for the Protection of Surface Waters." 010471 (Jackie Speight, Moore Co.) - the project is within WS-II HQW. The Foxfire Village Planning Dept. must review for variance process if it's a private rd. 010559 (Spangler Environmental, Wake Co.) - -40% of the project is within the WS-III Lake Benson balance of watershed. If this road is a private road, then it will need to go through the variance process with the Gamer Planning Dept. If it is a public road, road crossings are allowed if no practical alterfiative exists. Plus BUA must be minimized, stormwater diverted away from surface waters, and DOT must follow their document "BMPs for the Protection of Surface Waters." 010462 (DOT, Madison Co.) - the project is within WS-II. DOT must minimize BUA, divert stormwater away from surface waters, and follow their document "BMPs for the Protection of Surface Waters." 010474 (S&EC, Inc., Franklin Co.) - the project is within WS-11. If this road is a private road, then it will need to go through the variance process with the Youngsville Planning Dept. If it is a public road, road crossings are allowed if no practical alternative exists. Plus BUA must be minimized, stormwater diverted away from surface waters, and DOT must follow their document "BMPs for the Protection of Surface Waters." 010502 (Allen Smith, Durham Co.) - the project is within WS-IV. If the project doesn't need a sedimentation and erosion control plan, then state WSWP rules do not apply; however, the local WSWP program may be more protective. Consult with Durham Planning Dept. 010518 (John Corey, Pitt Co.) - lack of sufficient site map; questionable if within WS-IV. If the project doesn't n6ed a sedimentation and erosion control plan, then state WSWP rules do not ",.-- apply; however, the local WSWP program may be more protective. Consult with Pitt Co, or 1? Greenville Planning Dept. 010496 (S&EC, Inc., Durham Co.) - the project is within Falls Lake WS-IV. If the project doesn't ,s4i` need a sedimentation and erosion control plan, then state WSWP rules do not apply, however, the local WSWP program may be more protective. Consult with Durham Planning Dept. If applies, " the the crossings are public projects, then its allowed with min of BUA, divert stormwater, BMPs used. 010498 (Bridgewater Co., Iredell Co.) - the project is within WS-IV-CA of Lake Norman. If the project doesn't need a sedimentation and erosion control plan, then state WSWP rules do not apply; however, the local WSWP program may be more protective. Consult with local Planning Dept. Also, do Catawba Temp Rules apply? 010539 (DOT, Clay Co.) - the project is within WS-IV and a SEC plan is required. Therefore, a public project crossing is allowed if no practical alternative exists. BUA must be minimized, stormwater diverted, and DOT BMP document followed. 010547 (Griffin Contractors, Avery Co.) - no map, but the project is potentially within HQW and Tr and maybe even ? VS-IV. 010659 (DOT, Jackson Co.) - the project is within WS-III, ORW, and Tr. Crossings allowed if no practical alternative exists. BUA must be minimized, stormwater diverted, and DOT BMP document followed. 010554 (DOT, Durham Co.) - the project is partially within WS-III and partially within WS-III-CA. The CA must be avoided. If not, show avoidance and minimization. BUA must be minimized, stormwater diverted, and DOT BMP document followed. 010552 (David Duncan, Buncombe Co.) - Gap Creek is C Tr. No WSWP comment, but the design shows no structural benefit to the applicant and impacts to troutwaters. Projects Reviewed.
